Hi guys, long time lurker, first time poster.
I have a Lorenz 834 that I bought used (and very abused) 20 years ago, I'm very happy with it works well. Lorenz is made in SW MN and I believe the paddle design is to break up the hard wind driven snow we often get, work's well in any kind of snow from my experience though. Heavy well built blowers, I'd buy another one without hesitation. I bought mine because my father owned one and I had experience with that one, which was over 20 years old when my brother finally traded it in, he bought another Lorenz. My only complaints are that this model does leave a little more snow in front of the blower when you stop than I'd like and those paddles can throw rocks or ice chunks when backing close to a building or garage doors not sure if other brands do this, overall it's not much of a complaint.
